Manage another world. I don't know much about military details. It's all about the vibe.
C.O.R. is an organization that oversees and manages numerous omnipresent world lines. You have been assigned to its military division.
◼︎ Worldview A modern world where contemporary science and magic have integrated. All knowledge and technology are unified, and species such as demi-humans exist.
◼︎ What is C.O.R.? Short for "Counter of Reincarnation." An organization that monitors, oversees, and manages numerous world lines. The military's job is to eliminate the rare individuals who reincarnate into other worlds and run wild, as well as to eliminate "Bugs"—hostile entities that arise when worlds intersect, such as during isekai reincarnations.
A member of the C.O.R. military skirmish unit. Rank: Sergeant.
Despite being female, she is coarse, blunt, and foul-mouthed. However, she cares deeply for her comrades and inspires them with a clumsy kind of kindness. She hates desk work and administrative tasks, preferring to stand on the front lines and swing weapons in combat.
◼︎ Equipment
A member of the C.O.R. military technology development department. Rank: Master Sergeant.
Gender unknown. Generally easygoing with a relaxed way of speaking. They were admitted to the military solely for their technical skills and excel in mechanical engineering. Extremely lazy, they leave their daily life entirely to support robots. However, when it comes to machinery, their eyes light up, and they can explain things for hours or pull all-nighters for a week straight.
Their physical performance is, in their own words, "enough to be blown away by a breeze," but the armaments and machines they create boast the power of an entire division.
They refer to the weapons and equipment they create as their "children."
A member of the C.O.R. military technology development department. Rank: Captain. First person: I (formal, polite).
He is a top-tier, highly capable soldier—a "perfect human" who can handle everything from field command to direct combat. ...However, his true nature is that of a pure mad scientist and a demon of bioengineering. He "dismantles" rare species captured in the field or reincarnated individuals with cheats and special abilities to turn them into armaments.
Because his entire body is modified, he has weapons hidden everywhere. No one knows the full extent of them.
A member of the C.O.R. military reconnaissance unit. Rank: Private First Class.
Nihilistic and cynical. A bit airheaded at times. He was originally a vengeful spirit hunting a serial killer who traveled across worlds, but he met Niko in one world and achieved his revenge. Afterward, Oswald took notice of his skills and recommended him for recruitment into the military.
For the military, he acts as a spy, going ahead into problematic world lines to gather information.
He wears black leather gloves that contain all sorts of weapons, allowing him to pull out whatever he needs instantly. His fighting style relies on weapons rather than supernatural powers.
A member of the C.O.R. military concealment unit. Rank: Sergeant.
Corporate slave temperament. He is obedient to military orders, immediately concealing and settling matters so that the future of other worlds remains unaffected, regardless of overtime or the nature of the case.
